STEAM AND WATER SEPARATOR.

Application filed June 19,

To all whom it may concern: i

Be it known that we, ARTHUR L. PRoU'r and ADRAIN R. RnYNoLos, citizensof the .lllltGCl States, residing atLong Beach, in the countyof LosAngeles and State ofCah- 10111121, have invented new and usefulImprovements in Steam. and Water Separators, ot which the following 1s aspecification.

This invention is a steam and Water sep-- arator and consists of thenovel features herein shown, described and claimed.

An object 1s to make an lmprovement over an'ordinary steam trap andwhich will more efl eetually separate the water from the steam, asrequired to feed dry steam to an engine or the like. Another object isto make a device of the class described, which may be readily adjustedtori various steam pressures.

Another ob ect is to make a device of the "class described having meansfor indicating a leak in the float.

Another object is to make a steam and water separator for engines andthe like which will'carry lubrication to the steam chamber.

Other objects and advantages will appear from the drawings andspecification. The drawings illustrate a steam and water separator andlubricator embodying the principles of the invention. I

Figure 1 is-avertical diametrical'sectional elevation of the steam andwater separator. Fig. 2 is a view analogous to 'Flg. 1 and 1 showing amodified construction.

Fig. 3 is a view in elevation of the steam and water separator and thelubricator, the View being taken looking in the direction indicated bythe arrow 3 in Fig. 4.

Fig. 4 is a top plan view as indicated by. the. arrow 4 in Fig. 3, partsbeingbroken away and shown in section.

Fig. 5 is a horizontal sectional detail on the lines5-5 of Figs. 1 and 3and looking downwardly as indicated by the arrows.

The details of construction and operation shown inthe drawings are asfollows:

A cylinder 1 has an outturned flange 2 at its upper end, an inlet nipple3 below the flange 2 at one side and'an-outlet nipple 4 below the flange2 diametrically opposite the nipple 3 and the lower end of the cylinder1 has a tapered portion 5 leading down to a nipple 6 weldedto the lowerend of the tapered portion. A plug 7 is screwed upwardly into the nipple6 and has a spider 1924. Serial No. 720,914.

8 across its center and a valve seat 9 at its upper end. The outlet pipe1.0 is screwed into the lower end of the plug 7. The valve 11 has a headfitting upon the seat9 and a stem 12 sliding through the spider 7. Aball 13 is formed upon he upper end of the valve stem above the head 11and fits in a ballsocket 14 upon the lower end of the float stem 15. Thefloat stem 15 has a hollow16 extending upwardly from the socket 14 tothe upper end of the stem. The float17 is fixed upon the lower half ofthe stem 15, there being perforations 18 in the stem 15 within the float17 sothatif steam leaks into the float 17 it will blow out of the top ofthe stem and indicate that the float is leaking.

A cap 19 fits upon theupper end of the cylbar 22 fits upon the upper endof the stem 15 above the stuffing box 21 and a nut 23 is screwed. downupon the stem against the cross bar 22. Posts 24 and 25 extend up-'wardly from the cap 19 through springs 26 and 27 and then through the.cross bar 22 so that by adjusting the nut 23 the tensions of the springs26 and 27 are. adjusted to properly support the cross bar 22 and supportthe valve 11 with proper tension and the nut 23 may be readjustedforvarious steam pressures.

A cylinder 28 extends downwardly from the cap 19 and is spaced from thecylinder 1 to form ahcirculating chamber 2-9 outside of the cylinder,and a spiral baffle 30 is mounted around the cylinder 28 in the chamber29. An inlet port 31 is formed through the cylinder 28 near its upperend and directly opposite the inlet nipple 3, and an 1 outlet port 32 isformed through the cylinder 28 near the bottom 33, and .ports 34 areformed through the bottom. A battle or casting 35 extends downwardlyfrom the cap' through the pipe to suiiicient extent, the

float 17 will go down and close the valve 11. The steam pipe from aboiler is to be connected to the nipple 3 and the dewatered .;team willpass through the nipple 4 which is to be connected to an engine cylinderor the like.

In the nmdilication shown in Fig. 2, the angle iron battles 37 may besecured to the inner face of the cylinder 1 instead of the coil battlemounted upon the cylinder 28. The specific form of battle is immaterial.

The cylinder 1 is mounted upon the legs 38 and is adapted to maintain anupright position.

Referring to Figs. 3 and 4, the small tank 39 is adapted to be mountedupon the outside of the cylinder 1 by straps 40 and 41. A branch steampipe 42 leads from the nipple 3 to and through the top of the tank 39and to near the bottom of the inside of the tank. A pipe 44, including aneedle valve 45, an outlet check valve 46, and a sight feed gauge 47, isconnected through the top of the tank 39 and connected in the nipple 4so that steam pressure going through the pipe 42 will be discharged tothe bottom of the stock 48 of lubricant and the steam will bubble upthrou h the lubricant and become saturated with rubricantand pass intothe nipple 4 to be carried by the dewatered steam to the engine cylinderor the like. The flow of lubricant may be accurately adjusted bywatching the gauge 47 and manipulating the needle valve 45.

The upper ends of the posts 24 and 25 are screw threaded. Stop nuts 24and 25 are mounted upon the screw threads. A second cross bar 22 ismounted upon the posts against the nuts 24 and 25 and clamping nuts'24"and 24 are screweu down upon the posts 24 and 25 against the cross bar22. The cross bar 22 fits across the upper end of the stem 15 and isadjustably spaced therefrom to limit the upward movement or opening ofthe valve 11 and to limit the upward movement of the float 17.

Various changes may be made without departing from the spirit of theinvention as claimed.
